There are numerous applications for wireless sensor networks which are inevitable now a day in our daily life. Majority of such applications which use wireless sensor networks will be in areas where the direct human intervention is impossible. So the limited energy available in such sensors is a threat for prolonging the life of the entire network. The need(More)
The quality of service guaranteed multicast routing problem (QoS-MRP) is an important issue in wireless mesh networks (WMNs). However, the multicast routing is NP-complete problem. In this paper, this problem is transformed into a multi-objective combinatorial optimization problem. We present an improved discrete particle swarm optimization (PSO) approach(More)
